Connecting Two Devices Simultaneously (TX Mode)

The AK3040C can connect to two Bluetooth headphones simultaneously in Transmitter (TX) mode, allowing both to output audio with low latency. Follow the TX mode pairing steps for the first device, then repeat for the second device.

Underhåll

• Keep the device clean and dry. Avoid exposure to extreme temperatures, humidity, or corrosive substances.
• Försök inte att ta isär eller modifiera enheten, eftersom det upphäver garantin och kan orsaka skador.
• Använd endast den medföljande laddningskabeln eller en certifierad USB-C-kabel för laddning.

Felsökning

Inget ljud eller dålig ljudkvalitet

• Ensure both the AK3040C and your connected audio device (headphones/speakers/source) are fully charged.
• Verify that the 3.5mm audio cable is securely connected to both the AK3040C and the audio source/output device.
• Check that the AK3040C is in the correct mode (TX for transmitting, RX for receiving).
• Confirm that your Bluetooth headphones/speakers are properly paired with the AK3040C (in TX mode) or that your source device is paired with the AK3040C (in RX mode).
• Adjust the volume on both the AK3040C and the connected audio device.
• Move the devices closer to each other to ensure they are within the 10m communication range.
• Restart both the AK3040C and the connected audio devices.

Difficulty Pairing

• Ensure the AK3040C is in pairing mode (indicator light flashing).
• Make sure your other Bluetooth device is also in pairing mode.
• Clear previous Bluetooth connections on both devices and attempt to pair again.
• Minska störningar genom att flytta dig bort från andra trådlösa enheter (Wi-Fi-routrar, andra Bluetooth-enheter).

Audio Latency (Delay)

While the AK3040C supports APTX-Adaptive and APTX LL for low latency, some factors can still introduce delay:

• Ensure both the AK3040C and your connected headphones/speakers support APTX Low Latency or APTX-Adaptive codecs. If one device does not, it will default to a higher latency codec like SBC.
• The audio source itself might introduce delay (e.g., some projectors or older TVs).
• Environmental interference can affect latency.
